Striker Luciano Figueroa is at the centre of a dispute over his move to Birmingham after Spanish club Osasuna claimed they signed him before the Premiership club.

Figueroa, who joined the Blues last month in a &#xA3;2.5m deal from Argentinian side Rosario Central, could be forced to leave St Andrews after Fifa became involved in the affair.

Figueroa was signed when Steve Bruce and his players were in Malaysia for the Asia Cup.

But, despite playing as a second-half substitute in the friendly against Mallorca, Figueroa was left out of the squad for the 1-0 home win over Tottenham on Saturday. And Osasuna now claim that Birmingham have offered to sell the player to them if they match the price paid to the Argentinian club.

Osasuna claim Figueroa had signed a contract with them on July 10, before signing a contract with Birmingham on July 23.

An Osasuna statement said: "Osasuna have received a document from Birmingham City in which they have communicated that they do not wish to have any conflict with Fifa, nor with Osasuna."

Losing Figueroa would be a blow to Birmingham, whose French striker Christophe Dugarry will be out for a month after undergoing a minor knee operation yesterday.
